"Look at me Levi," Eren whispered wrapping his sensuous fronds delicately around Levi’s long hard spout. "Look how wet you’ve made me. Let me suck it all up baby, shower me with it, more, more!" He screamed through his stomata.

WHAT’S THAT?Found on the underside of leaves, stomata are like pores in our skin. They are tiny openings that allow for gas exchange so plants can make food and cool off from heat. In this magnified image of a wandering jew plant, stomata (in green) are surrounded by leaf cells (in purple).

WHAT’S THE LATEST?Carbon dioxide (CO2) levels in the atmosphere have been increasing decade after decade, and plants aren’t sure how to deal with it. When CO2 levels are high, plants reduce their number of stomata. With less stomata, plants can’t cool off by releasing water to evaporate, so they die from heat stress during heat waves and droughts. Researchers at UC San Diego have found a new genetic pathway that controls stomata numbers in response to CO2 levels, which could help scientists engineer plants that can withstand harsh conditions in changing climates.

Plants take in gas through their stomata (small openings typically found on the underside of leaves), making them the site of gas exchange. Plants require both oxygen and carbon dioxide to perform their everyday chemical processes, though they use more carbon dioxide. Stomata are also important in transpiration: the evaporation of water through the leaves, which creates a pull throughout the plant’s vascular tissue, allowing water to move into the plant through the roots. This is called the transpiration stream.

Stomata can open and close by changing the amount of water in the two cells that sit on the sides of the stomatal opening. Doing so can help preserve water in the plant. [x]

“I want to venture through untouched lands and witness how I can be part of the forest and feed the plants with my own breath. One day I will overcome all fear of things living and let my blood nourish the buzzing mosquitos. I will let the vines envelope my rotting bones and disappear into the soil. The day I succumb to the frigid temperature of the river is the day the forest will no longer recognize me as foreign.”

3. Mata: Kapai Summer Session IPA. session just means low alcohol. So you can drink more I presume. Is good. Not *stupid* good, but I would drink 6 of these. Clean. Pure. A very natural taste. Good maybe for people who don’t like too strong hops? Try once.

Abstract: Feedbacks from terrestrial ecosystems to atmospheric CO2 concentrations contribute the second-largest uncertainty to projections of future climate. These feedbacks, acting over huge regions and long periods of time, are extraordinarily difficult to observe and quantify directly. We evaluated in situ, atmospheric, and simulation estimates of the effect of CO2 on carbon storage, subject to mass balance constraints. Multiple lines of evidence suggest significant tropical uptake for CO2, approximately balancing net deforestation and confirming a substantial negative global feedback to atmospheric CO2 and climate. This reconciles two approaches that have previously produced contradictory results. We provide a consistent explanation of the impacts of CO2 on terrestrial carbon across the 12 orders of magnitude between plant stomata and the global carbon cycle.

stomata are found on the underside of the leaf and allow for diffusion of water and gases in and out of the plant

during the day, the stomata open. water moves in by osmosis from the mesophyll cells, causing the guard cells to bend and open. open stomata allows for carbon dioxide to diffuse in for photosynthesis, and for water to evaporate out, cooling the plant down

during the night, the stomata close. water no longer passes out of the plant, stopping transpiration, as the plant does not need to be cooled down. carbon dioxide cannot be diffused in, so photosynthesis does not take place
